I hope you read the post about how to make the batwings. If you would like to fly..wear them, then you need something to secure them to your body. I cut 2 yards of black cotton fabric 3 inches wide stripes. Fold the stripes once and sew along the edge to make neat but sturdy ribbons. I had my velvet jacket on my dummy and it was perfect because the ribbons didn't slip. Put them over the shoulders. Hold the batwings against the back and check how you want them to be placed. I made an angled fold on the strips pinned and sew like the picture below.

The batwings are sewnd by hand to the ribbons, with many many stitches to secure them properly. You want them to look like you are ready to take off, right? As you see on the pictures I wrapped a rag around the middle to hide the metal threads (before stitching them to the ribbons).
